| hexa | running into this situation on nixos 25.11 in nixos/infra | 23:00:40 |
| hexa | why does the nix team not own the nix module? https://github.com/NixOS/nixpkgs/pull/440438 | 23:28:36 |
| hexa | culprit was https://github.com/helsinki-systems/hydra-queue-runner/blob/master/builder-module.nix#L278 | 23:43:16 |
| hexa | which likely does not compose | 23:43:27 |
 Sergei Zimmerman (xokdvium) | Ordering of options might matter? | 23:44:06 |
| hexa | if it did that would be wild | 23:44:23 |
| Sergei Zimmerman (xokdvium) | extra- appends probably but the regular experimental-options sets it? Dunno, just a hunch | 23:44:52 |
| Sergei Zimmerman (xokdvium) | But that would be in-line with my expectations | 23:45:07 |
| hexa | https://github.com/helsinki-systems/hydra-queue-runner/pull/5/changes/7184ac1e00b1cb87f1c583325758b27b2da1a939 makes it work | 23:48:09 |

 dramforever | today i learned that binfmt-misc can be set per-userns https://github.com/torvalds/linux/commit/21ca59b365c091d583f36ac753eaa8baf947be6f | 17:36:56 |
| dramforever | i wonder if anyone has looked into using this to isolate emulated builds. currently having binfmt-misc emulators enabled contaminates all the build sandboxes. if we can run builds each with a different set of binfmt-misc emulators that would be a huge improvement over the status quo (and i can get over my fear of enabling emulators on my machine) | 17:38:53 |
| dramforever | seems like we already run builds in a new userns if possible? | 17:40:27 |
 K900 | I do not remember how but binfmt userns is somehow fucked | 17:45:13 |
| dramforever | can we at least disable them for non-emulated builds or something | 17:47:14 |
| dramforever | well, guess i'm going to be wasting weekends looking into how fucked it is | 17:51:56 |
